I'm afraid all of those things have variables. The oil pressure will vary greatly with temperature, RPM and oil viscosity. About 7-8PSI is the minimum acceptable. Temperature should remain around 195 to 200 when the car is cruising but could climb to near 230 in slow traffic situations because that's the way the electric fan is programmed. The idle is entirely controlled by the computer and will vary with conditions and temperature.
